There is a warning being circulated over a new phone scam where cold callers ask: 'Can you hear me?'.

Scammers are reportedly targeting unwitting Brits by recording responses in a bid to then defraud you.

Those behind the scam ask “can you hear me?” and then record your response the crooks supposedly use this recording as a voice signature to charge you for products and services you never actually used.

If you then try to disagree with them, they reportedly play back the recording of you saying ‘yes’ and threaten to take legal action if you don’t pay up.

Victims report they receive a call from a local number before the person on the other end of the phone introduces themselves and the company they apparently work for

They then say “can you hear me?” and your answer is recorded and your response will be edited and used to charge you for products or services without your knowledge.

Some experts have questioned whether the scam is actually real - and even suggested there are no reported cases of it being used succesfully.

Hoax-busting website Snopes.com has marked the scam as “unproven” and has raised questions about how the scam would work in reality.

The website points out that in order to charge you, the scammers would have to have access to your debit or credit card details.

It then goes on to say researchers working for Snopes “haven’t yet been able to identify any scenario under which a scammer could authorize charges in another person’s name simply by possessing a voice recording of that person saying ‘yes.’”

Snopes also pointed out that anyone quoted in such stories have merely reported being asked the question rather than actually falling victim to the scam.
